Map My Contacts

Visualize the location of your Google Contacts on a Google Map.
The Google Contact add-on uses an open-source Google Script to read the postal addresses associated with your contacts and then geocodes the address using Google Maps' Geocoding API. The generated Google map and the associated KML file are placed in your Google Drive that you can access in any web browser.
The free version can process up to 200 Google Contacts. Go pro if you would like to process all your contacts.
